VIOLENT AND GENTLE SHOWERS
Right here let the reader CLEARLY
understand why We have gentle ard
violent showers. When the air is s'ill
and cools near the earth We have only a
fog. When small currents Of different
temperatures meet here and there in
the upper regions We have separate
clouds. When larger, slow moving
masses of air of two temperatures meet,
we have the heavens covered with clouds.
When the winds drive together consid-
cradle masses of air differing a good
deal in temperature, the giving up Of
watery PARTICLES by the mass Of warm
air, quickly cooled, is so great that rain
results. But if two swiftly moving
masses of hot and cold air come sudden
ly together, there is SO much water
given up that we have quick, violent
rainfall. That happened yesterday
afternoon, right where We are, on the
plains of Western Kansas. The day
was excessively warm with scarcely a
breeze. and the hot air rose high up.
At SIX o clock r. NJ; from some cause
current of cold AIR came from the
northwest with great velocity. There
we're no mountains or forests on the
level plains to check its rapid fight.
As it rushed into the hot air above us,
so much of it was suddenly cooled that
the rain came down almost in a sheet.
The swift air current had gone by be-
fore the rain drops had time even to
reach the earth, and there was but one
dash. In ten minutes the sky was en-
tirely clear, but the atmosphere was
wonderfully cooled. If there had been
on the plains any trees, fences, houses,
tall grass, corn or other crops, any or
all of these would have helped check the
swift air or wind current at every mile
and rod; it would have moved so much
slower that our dashing sheet Of rain
would no doubt have been prolonged to
a gentle drizzling shower of perhaps an
hours duration. The drizzling water
would have had time Is sink into the
earth. Asst was, the sheet Of water
ran in torrents down into the :'draws"
or hoilows, aud off to the river.
Though an iuch of rain fell, on going
out and examining some prairie sod,
VIC found it not even moistened half an
inch deep. There was water enough fell
to have penetrated foot deep, if it had
had time. We repeat to fix it in the
mind for use further on, that if there
had been anything, even tall prairie
grass extending dozen or twenty miles
to the northwest of US, that wind cur
rent would have chafed against it. and
been slowed down, 50 that the sheet
rain would have been 80 slow and gentle a
shower that the soil could have absorbed
most of it. and stored it for the roots
Of plants.
MOUNTAINS STEALING MOISTURE.
If the reader now understands that
any cooling of the air makes it give up
drops Of water, or watery
vapor, it will be easy to see why there
is an arid belt along the eastern side of
the Rocky Mountains and Sierra New
adas The suns rays do not warm pure,
air in passing through it.
The rays, when absorbed by the earth,
warm that. The air touching the sur
face is warmed by it, and becoming
lighter by the expansion. it rises up
ward until: it gets cooled down by MN
Cling with the cold upper air. As it
rises other cold air flows into its place,
gets warmed and also rises, and this
keeps being done right at the earth's
surface. But not enough AIR gets thus
warmed to rise very high. OnIy a few
miles above US, it is probably always
colder than at the North pole. If We
could travel towards the moon, we
should freeze Is death in the cold air
before we had gone ten miles away from
the earth. So it is that on mountains
from four or FIVE miles high, it is 80
cold that snow never melts. The tops
of mountains only couple Of miles
high are very much colder than the
lower ground. Now most of the winds
in the regions named above, blow from
west to east. In passing over the
and Sierras, they are SO cooled
that they give up good deal Of their
water, and have little to spare
until they arc replenishcd. These cool
tops thus steal the moisture
